Expression and secretion of the S2 subunit of pertussis toxin in Bacillus brevis.


We have been trying to develop a mass production system for each of the subunits (S2, S3, S4, S5) of the pertussis toxin B oligomer (PTB) by using a Bacillus brevis-pNU212 system. In consequence a moderately efficient expression-secretion system for S2 was constructed by fusing the mature S2 gene from Bordetella pertussis Tohama with the signal-peptide… (More)
